Abstract
Percutaneous lumbar posterior medial branch neurotomy is a technique for the treatment of lumbago which is caused by irritation of the posterior medial branch. The needle electrode was located in the groove between mamillary process and accessory process by anteroposterior fluoroscopy. To destroy the nerve a lesion was made with a radio-frequency generator (10W, 20sec, 2times). 32 patients of lumbar facet syndrome and one patient of lumbar spondylolysis were treated with this technique. 20 cases had good clinical course. The cases of multiple facet pain and psychogenic low back pain had poor result.
